Multithreading and concurrency enhance the performance and responsiveness of Java applications by allowing multiple tasks to be executed simultaneously. The chapter covers fundamental concepts such as thread creation, life cycles, scheduling, synchronization techniques, and the significance of utilizing concurrency utilities. Best practices for safe and effective concurrent programming are also emphasized.
Java supports multithreading natively, allowing the execution of multiple threads.
Concurrency can improve application performance but requires careful management of shared resources.
Using the java.util.concurrent package facilitates better concurrency management with higher-level constructs.
A lightweight subprocess that shares the same memory space but executes independently.
The various states a thread can be in, including New, Runnable, Running, Blocked/Waiting, and Terminated.
A method to control access to shared resources by multiple threads, preventing race conditions.
A high-level utility for managing and executing asynchronous tasks via thread pooling.
A situation where multiple threads access and modify shared data simultaneously, leading to inconsistent results.
A condition where two or more threads are waiting indefinitely for resources held by each other.
Variables that support lock-free, thread-safe operations for counters and updates.
